Cosmetic effect of coconut oil

Coconut is not only delicious, but also an important woody oil crop. Mature pulp through dry or other pre-processing, and then through pressing, solvent treated or centrifuged, can be obtained coconut oil. First squeezed coconut oil is pale yellow, with coconut flavor, people were loved it. Refined coconut oil is white. 

In coconut oil, the saturated fat content was up to 90%,

so coconut oil's melting point is higher than the melting point of common

edible oils, it itself at room temperature is solid. Apart from the saturated

fatty acid esters, coconut oil also contains small amounts of unsaturated fatty

acid esters, free fatty acids such as lauric acid and other ingredients.

Most people use coconut oil on the skin to maintain moisture. We

should know that, the less water content of the stratum corneum, the skin will

more dry; if reduce water losing from the stratum corneum, the skin's dry

condition can be improved. 85% or more components of coconut oil are a lot of

saturated fatty acid esters, the closed skin effect is similar to petrolatum,

mineral oil, can reduce transepidermal water losing, play a moisturizing

effect. Coconut oil also can increase the skin surface lipids, soft skin. That

is to say coconut oil is only a humectant. While substances which really have

nutritional function to skin such as unsaturated fatty acids, vitamin E and the

like are accounted for very small amounts in coconut oil, so coconut oil is not

anti-aging, removing wrinkles and other skin care effects.

Directly applied the coconut oil, especially unrefined coconut oil

to the face or hands may be risky. Free lactic acid contained in coconut oil

may cause irritation to the skin. Studies have shown that lauric acid has small

molecular weight, can easily be dissolved in the lipid phase and permeate the

membrane, physical damage to the cells, and inhibit the production energy and

transfer nutrients enzymes, resulting in reversible and irreversible changes,

lead to cell death. Only the lauric acid reacted with diethanolamine to produce

Coconutt Diethanol Amide

can be used as cosmetic additives.

Coconut oil is important indirect materials in the cosmetics

industry, such as for soap industry. Coconut oil's saponification value is

higher than other common vegetable oils, freezing point in 21~25,

made of soap would not too soft, and foaming well, very suitable for simple

hand cold soap. Of course, this handmade soap is not healthier than ordinary soap.

Hair is divided into three kinds from outside to inside, namely,

hair cuticle, hair cortex and medulla hair, whose main ingredient is keratin.

Damaged hair mainly refers to the cuticle under physical and chemical action,

generates friction, deformation, while the coconut oil conditioner role is

reflected in its attentive care on keratin. For all kinds of hair types,

coconut oil has prevented combing injury effect. It can form lubricating film

on the surface of the hair, reduces the friction between the hair cuticle, even

have the effect on damaged hair.

Used coconut oil before the washing hair, it can form a hydrophobic

film on the keratin edge, prevent hair absorbing water; and it can penetrate

into the hair, reducing the swelling extent of keratin. Hair absorbs less

water, hair cuticle deformation and friction damaged will be reduced, the hair

is protected. Lauric acid in coconut oil has a strong affinity to keratin,

meanwhile it is amylose molecules of small molecular weight, which can permeate

the hair fiber. Mineral oil and other vegetable oils cannot penetrate into the

hair.

All in all, coconut oil is a good cosmetic raw material, but it should not be given too much expectations, it cannot

anti-aging also can not remove wrinkles.
